If you like her I would keep her, but try to work out some other deal with him for something else maybe? I personally wouldn't breed her in the future, and just keep her as a pet (especially if she's a sweetheart!). And then if you wanted to work with boa projects in the future, I would look into getting one from a really reputable boa breeder. There are a lot of stunning boas out there from really awesome breeders. I don't see them around here, but if you poke around on some boa enthusiast sites you'll find some drop dead gorgeous BCCs out there. But if you just want a pet she is very pretty.
